We look at the division of 87108148 by 168 
The aim is to understand the frequency of 168 in 87108148.

Going ahead to step 1:
If we divide 8 by 168, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 168

Let's proceed to step 2:
168 goes into 87 0 times with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Fetch the next digit (1) from the dividend, attach it to 87 and continue: 871 / 168

On to step 3:
168 can be fit into 871 5 times, resulting in a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 840 from 871, we get 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 168

On to step 4:
The number 168 fits into 310 1 times, leaving a remainder of 142.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtracting 168 from 310 leaves us with 142.
Append the next digit (8) from the dividend to 142 and continue with: 1428 / 168

Going ahead to step 5:
168 goes into 1428 8 times with a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 518.0
Deduct 1344 from 1428 and we're left with 84.
Append the next digit (1) from the dividend to 84 and continue with: 841 / 168

Going ahead to step 6:
If we divide 841 by 168, we get 5 and a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5185.0
If we take 840 away from 841, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 168

Moving on to step 7:
If we divide 14 by 168, we get 0 and a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 51850.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 168

On to step 8:
If we divide 148 by 168, we get 0 and a remainder of 148.
The number 0 becomes the next digit in our result. 
Result so far: 518500.0
Subtracting 0 from 148 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 9:
1480 divided by 168 is 8 with a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 518500.8
Subtracting 1344 from 1480 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 10:
If we divide 1360 by 168, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 518500.88
If we subtract 1344 from 1360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 518500.88 with a remaining 0.016.
